Here is a sample of XSD code:
<?xml version="1.0" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
. . .
</xsd:schema>
Question 1. Given the following XML code containing an exam result where score is an integer; and contestant id, exam id, band and digital signature are strings. Your task is to write the corresponding XSD code and save it into the file q1.xsd.
<?xml version="1.0"?>
<result ref="10007629P">
<contestantId>00025142</contestantId>
<examId>KB253DG</examId>
<score>156</score>
<band>C</band>
<digitalSignature>a720cf8e23bc1256bce2</digitalSignature> </result>
Question 2. Copy the code from q1.xsd to q2.xsd. In q2.xsd, add the following restrictions:
● Band values must be A, B, C or D.
● Score values must be an integer between 0 and 300.
Here is a sample of restriction code:
<xsd:restriction base="xsd:integer">
<xsd:minInclusive value="0" />
<xsd:maxInclusive value="100" />
</xsd:restriction>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="LARGE" />
<xsd:enumeration value="MEDIUM" />
<xsd:enumeration value="SMALL" />
</xsd:restriction>
